VALVE Application filed November T0 aZZ whom it may concern: I

Be it known that I, HUGH I. JORDAN, residing at Staunton, Virginia, acitizen of the United States, have invented certain new and usefulImprovements ,in Valve Lifters, of which the following is aspecification.

My invention relates to tools for use in compressing the seating springsof poppet valves of internal combustion engines to enable thereadyremoval of the valves, and my invention is embodied in that form ortype of tool which comprises two members one for engaging the valve headand the other for engaging the spring washer and such a connectionbetween the two members as will permit the movement of the springengaging member in the direction to compress the spring. My invention inwhat I consider its best embodiment gives the advantages of abilitytouse the same tool with the valves of a variety of engines, rapidity ofmanipulation so that a valve may be removed in short time, and ease ofMy invention consists in whatever is described by or included within theterms or scope of the appended claims.

In the annexed drawings:

Fig. 1 is a perspective view, of a tool embodying my invention, and Fig.2 is a side elevation, the full lines showing the position of parts whenthe tool is applied and the dotted lines showing their position whenthe.

valve spring has been compressed.

Referring in detail to what is shown in the drawings, the member of mytool which is engaged with the top of the valve head and which forms thesupport upon which the movable spring compressing member moves comprisesa shank, 10, that may be a flat metal bar which at the valve engagingend is pointed to engage the usual hole in the top of the head, and, atthe other end is provided with a handle, 11, for the comfortableengagement, say the left'hand of the workman to place and hold the toolin position. The spring engaging member, 12, is substantially C-shapedso that with its lower spring washer engaging end thrust beneath suchwasher it will clear the manifold, and near its upper end is pivotallyconnected with a hand lever, 13, which at one end by a pivot, 14, isfulcrumed on the support, 10, and at its other end has a handgrip, 15,to enable the workman comfortably menses PATENT OFFICE.

to press upward on the lever, and thereby move upward the spring washerengaging lower end of the member 12. Preferably the member, 12, is madeof two similar flat metal bars, which lie one against the otherthroughout their extent, except at the lower end of the member wherethey diverge into a V-shape so that they may straddle the spring washerand each fork or arm of the V hasan in'turned flange, 16, to catchunderneath said washer. At the vpoints of diver- 'gence of the forks orarms is a bolt 17, by which to adjust the distance between the arms tosuit washers of different diameter, normally the forks tending to springapart from the natural spring of the bars that form the member, 12. Atthe point of connection of the operating lever, 13, with the member, 12,the latter passes betweenthe two parts that form the member, 12', sothat the connection between the lever and the, member, 12, is a singlelink, and not a pair of links which would add to the cost and weight ofthe tool.

From the. pivot, 18, which connects the lever, 18, and member,'12,the/latter is extended upward and at the extremity thereof by a pivot,19, one end of a link, 20, is connected, the other end being connectedby a pivot, 21, to support 10, and thus the support, 10, and the member,12, are so connected together that they are readily maintained inrelative position, and thus convenience of handling the tool ispromoted. There is but a single link, 20, in the interest of producingmetal and thus saving cost and weight. The link, 20, is also utilized asa part of a latch deviceto secure the spring compressing member, 12, inspring compressed position so as to leave the hand of the workman freeto remove the pin or other device on the valve stem when it has beenfreed from the pressure of the spring. Said. latch device comprises arack bar, 22, which is pivoted to the support, 10, and a stud, 23,

on the'link, 20, with which the teeth of the rack may engage, the rackhaving a hand member, 24, which extends alongside of the support handle,11, so that the hand grasp- .ing the handle, 11, may readily release therack from the stud,'23, with which it is yieldably engaged by a spring,25, interposed between the support, 10, and the rack member, 24. Therack engaging stud, 23, may be one end of a loop, 26, that confines therack, 22, in position while allowing it enough freedom to swing into andout of engagement with the stud, 23.

It is important that when the spring compressing member 12, is moved inthe direc tion to compress the spring that the forks or arms be kept incontact with the washer; I maintain such engagement and assure it byproducing a tendency of the washer engaging arms to move in .theopposite direction from that which would slip them from beneath saidwasher, and I accomplishthat result by making the link between thepivots,

'14, and 18, longer than the link between the pivots, 19, and, 21, sothat when the operating lever, 13, is moved upward from the fulllineposition of Fig. 2 to the dotted line position of Fig. 2, the pivot, 18,between the lever, 13, and the member, 12, will move towards the supportmember, 10, and thus the spring compressing member, 12, will be moved ortend to move to carry its washer engaging arms into more secure contactwith the Washer.

It is important that the line of thrust of the Washer engaging portionof the member, 12, shall be coincident with the axis of the valve stem,and the point of bearing con tact of the support member, 10, on thevalve head in order to prevent slipping o f the s rin com ressin' member12 off the b g 7 washer. To enable this condition to exist even whendealing with valves whose stems stand at an angle, I provide forchangeof the point of connection ofthe pivot, 18, 'between the lever, 14, andthe member, 12, the latter having several holes, 26, into any one ofwhich the pivot, 18, may be placed so as to vary the angle of thesupport, 10, with reference to the spring pressing member, 12.

What I claim is: r

1. A valve lifting tool comprising a support member having a handle atone end and adapted to engage a valve head, a spring compressing member,a lever having a handle and pivotally connected to both of said membersto form a link connection between them, a second link connection betweensaid members, the linkage between the two members being arranged tocause a tendency of the spring compressing member to remain in positionto act upon the spring, the spring engaging part of the compressingmember terminating in a free extremity which by such tendency isprevented from moving towards the valve stem.

2. A valve lifter comprising a support member having a handle at one endand adapted to engage a valve at the other end.

.a spring compressing member, the latter being formed of similar side byside bars that diverge to provide supporting arms adapted to straddleth'e'valve stem, "a pair of links connected with the support and thespring compressing member at different points,'one

of said links passing between the two parts that form the springcompressing member,

means to move the spring compressing member on its pivotal connectionwith the support member, and a latch device between the support memberand one of said links.

3. A valve lifter comprising a support member having a handle at one endand adapted to engage a valve head, a spring compressing memberterminating in a free end that engages the spring, a pair of linkspivotally connecting such members, the link pivots being sodisposed thatat all times during a spring compressing movement of the compressingmember its free end will tend to move in a direction opposite that forthe withdrawal of the same from the spring.

In testimony whereof I hereunto affix my signature.
